Another View: Aon Through a P/E Lens

A second take on Aon comes from its P/E ratio rather than cash flows. The stock trades on roughly 19.4x earnings, which is well above the US Insurance industry at 11.5x and the fair ratio of 13.7x, yet below a peer average of 26x. That mix can point to valuation risk if sentiment cools or opportunity if Aon continues to justify a premium. Which side of that tradeoff feels more convincing right now?
